These are completely new designs, designed by and manufactured exclusively for GroovyGameGear, with a classic look that many
have been asking for.

We're not sure who first thought of putting a
coarse diamond knurl on a spinner knob, but I think folks will find the
fine, vertical knurl on these knobs to be much easier on the fingers
while still providing a solid and reliable gripping surface.

The knobs are made of solid aluminum alloy and have a heavy anodize coating for superior wear and corrosion resistance.

These knobs are also compatible with GroovyGameGear's
Accu-Twist™ option (selectable above), which provides for user adjustable friction control to better simulate controls for games where free spinning may not be desireable.

Printed graphics with a clear
acrylic insert will be available soon for the Inset models.

See the TurboTwist2 Spinner options for a special discount on these knobs when ordered with our spinner control!
